To perform the Motor Speed Sensor Test
The Motor Speed Sensor test helps you determine whether or not there is a problem with the Platinum
Q|165 speed sensor.
 NOTE: Before performing this test, remove the bobbin case and the top thread.
• Press the Motor Speed Sensor button. Then press the Start button on the handlebars and the
machine needle will begin slowly moving up and down. The display will show a number that should
stabilize at 100 if the sensor is functioning properly. Press Start again to stop the machine and the
test.
To perform the Keypad Test
The Keypad test verifies that the Platinum Q|165 is reading the handlebar buttons when they are pressed.
• Press the Keyboard Test button. Then press one of the handlebar buttons. When you press the
key, the name of the key appears in a white box on the screen. When you release the key,
the name disappears.
To perform the Y-Motion Sensor Test
Use the Y-Motion Sensor test to verify functionality of the Y-axis stitch regulator encoder (the encoder
mounted to the rear side of the machine).
• Press the Y-Motion Sensor test button. Slowly move the machine toward and away from you. You
should hear a pulsing beep that pulses faster as you move the machine faster. A solid beep, no
beep, or periods of irregular beeping (with constant motion) indicate a problem with the Y-axis
encoder.
 NOTE: The most likely cause of a problem is a stitch regulator wheel that is not making consistent
contact with the track. Check the spring tension on the sensor assembly on the machine to assure
that it will easily return to the fully extended (down) position after being compressed. Also assure
that the track is straight with no dips or indentations and that it is clean and free of contamination.
Other causes are an unplugged or damaged cable or possibly an issue with the main control board.
To perform the X-Motion Sensor Test
Use the X-Motion Sensor test to verify functionality of the X-axis stitch regulator encoder (the encoder
mounted at the rear of the carriage).
• Press the X-Motion Sensor test button. Slowly move the machine left and right. You should hear a
pulsing beep that pulses faster as you move the carriage faster. A solid beep, no beep, or periods of
irregular beeping (with constant motion) indicate a problem with the X-axis encoder.
 NOTE: The most likely cause of a problem is a stitch regulator wheel that is not making consistent
contact with the track. Check the spring tension on the sensor assembly on the carriage to ensure
that it will easily return to the fully extended position after being compressed. Also ensure that the
track is straight with no dips or indentations and that it is clean and free of contamination. Other
causes are an unplugged or damaged cable or possibly an issue with the main control board.
